摘　　要：本文研究了城市轨道交通隧道在下穿重要建(构)筑物时的施工技术,结合超前预支护施工技术,包括超前小导管、大管棚和中管棚支护技术以及止水帷幕施工技术,详细探讨了隧道施工引起地表沉降的规律和对策。通过MATLAB绘制沉降变化图,直观展示了不同施工方式下的地表沉降变化,为隧道施工提供了理论和实践指导。In this paper,the construction technology of urban rail transit tunnel when passing under important buildings(structures)is studied,and the rules and countermeasures of surface settlement caused by tunnel construction are discussed in detail in combination with the advanced pre-support construction technology,including the advanced small conduit,the support technology of large pipe shed and middle pipe shed,and the construction technology of waterproof curtain.The settlement change diagram was drawn by MATLAB,which intuitively demonstrated the surface settlement change under different construction methods,and provided theoretical and practical guidance for tunnel construction.
